Customize the Virtual Machine Settings in the VMware Host Client
Before you deploy a new virtual machine, you have the option to congure the virtual machine hardware
and the virtual machine options.
For information about virtual machine options and virtual disk conguration, including instructions for
adding dierent types of devices, see vSphere Virtual Machine Administration.
Procedure
1 Congure the virtual machine hardware seings on the Virtual Hardware tab of the Customize seings
page in the New Virtual Machine wizard.
2 (Optional) To add a new virtual hardware device, select the device from the Add other device drop-
down menu on the Customize seings page of the New Virtual Machine wizard.
3 (Optional) Expand any device to view and congure device seings.
Option Description
CPU
The CPU or processor is the portion of a computer system that carries out
the instructions of a computer program and is the primary element
carrying out the computer's functions. CPUs contain cores. The number of
virtual CPUs that are available to a virtual machine depends on the
number of licensed CPUs on the host, and the number of CPUs supported
by the guest operating system. To use the VMware multicore virtual CPUs
feature, you must comply with the requirements of the guest operating
system EULA.
Memory
You can add, change, or congure virtual machine memory resources or
options to enhance virtual machine performance. You can set most of the
memory parameters during virtual machine creation or after the guest
operating system is installed. The memory resource seings for a virtual
machine determine how much of the host's memory is allocated to the
virtual machine. The virtual hardware memory size determines how much
memory is available to applications that run in the virtual machine.
Hard disk
You can add large-capacity virtual disks to virtual machines and add more
space to existing disks, even when the virtual machine is running. You can
set most of the virtual disk parameters during virtual machine creation or
after you install the guest operating system.
SCSI controller
Storage controllers appear to a virtual machine as dierent types of SCSI
controllers, including BusLogic Parallel, LSI Logic Parallel, LSI Logic SAS,
and VMware Paravirtual SCSI. You can set the type of SCSI bus sharing for
a virtual machine and indicate whether the SCSI bus is shared. Depending
on the type of sharing, virtual machines can access the same virtual disk
simultaneously on the same server or on any server. You can change the
SCSI controller conguration for a virtual machine on an ESXi host only.
SATA controller
If a virtual machine has multiple hard disks or CD/DVD-ROM devices,
you can add up to three additional SATA controllers to assign the devices
to. When you spread the devices among several controllers, you can
improve performance and avoid data trac congestion. You can also add
additional controllers if you exceed the thirty-device limit for a single
controller. You can boot virtual machines from SATA controllers and use
them for large-capacity virtual hard disks.
